Comparative long-term prognosis of acute myocardial infarction and acute aortic dissection in a population-based registry

Yuichi Sawayama, Akiko Harada, Naoyuki Takashima, Takashi Yamamoto et autres

Abstract Aims Acute myocardial infarction (AMI) and acute aortic dissection (AAD) are major cardiovascular emergencies with high mortality; however, their long-term prognoses have rarely been directly compared within the same population. Understanding differences in real-world outcomes between these conditions is important for …

Long-Term Clinical Outcomes With Defect-Free Care Adherent to the Performance Measures in Patients with STEMI Undergoing PCI in Japan

Hiroki Shiomi, Takeshi Morimoto, Manabu Ogita, Tomohisa Tada et autres

BACKGROUND: Adherence to the clinical performance measures has been advocated in ST-segment-elevation acute myocardial infarction (STEMI) care worldwide. We aimed to examine the association between adherence to these performance measures and long-term clinical outcomes in patients with STEMI undergoing percutaneous coronary intervention. …

Extended Anticoagulation Therapy With Rivaroxaban for Cancer‐Associated Low‐Risk Pulmonary Embolism According to Different Performance Status Scores: Insights From the ONCO PE Randomized Trial

Wei Xiong, Yugo Yamashita, Takeshi Morimoto, Nao Muraoka et autres

Background The ONCO PE (Optimal Duration of Anticoagulation Therapy for Low‐Risk Pulmonary Embolism Patients With Cancer) trial demonstrated the superiority of 18‐month compared with 6‐month rivaroxaban treatment for cancer‐associated low‐risk pulmonary embolism in reducing recurrent venous thromboembolism. However, it was uncertain whether …

Phenotypic Severity of SCN5A -Related Bradycardia Is Independent of Dominant-Negative and Coupled Gating Effects

Ayami Tano, Koichi Kato, Kohei Yamauchi, Hideyuki Jinzai et autres

BACKGROUND: Pathogenic SCN5A variants are associated with inherited arrhythmias such as long-QT syndrome, Brugada syndrome, and sick sinus syndrome. While Na v 1.5, an α-subunit of the cardiac sodium channel encoded by SCN5A , has been considered to function as a monomer, …

The impact of heart failure and bleeding risk on clinical outcomes in patients after percutaneous coronary intervention

Y Yazaki, Yoshihisa Nakagawa, Ken Kozuma, Raisuke Iijima et autres

BACKGROUND: In recent years, revascularization for ischaemic heart failure (HF) has received increasing attention, and percutaneous coronary intervention (PCI) has been positioned as a high-risk procedure. However, the risk of major bleeding and major adverse cardiac and cerebrovascular events (MACCE) after PCI …

Relationship between high platelet reactivity with Prasugrel and clinical events after percutaneous coronary intervention in patients with diabetes mellitus: A PENDULUM registry substudy

Daiki Yoshiura, Masanori Taniwaki, Yoshihisa Nakagawa, Ken Kozuma et autres

BACKGROUND: Patients with diabetes mellitus (DM) have a high risk of ischemic events after percutaneous coronary intervention (PCI). However, the relationship between high platelet reactivity (HPR) with prasugrel and clinical events in patients with DM remains unclear. This post-hoc analysis of the …

The velocity ratio as a predictor of valve calcium degeneration in aortic stenosis with low flow status

Hiroki Okamoto, Atsushi Hayashi, Jun Matsubayashi, Misato Kodama et autres

BACKGROUND: Determining the severity of aortic stenosis (AS) with low-flow (LF) status remains challenging because conventional echocardiographic indicators often yield discordant results. The velocity ratio (VR), in addition to the aortic valve calcium (AVC) score, has been proposed as a supplemental parameter …
